System.Runtime.Versioning Namespace

Contains advanced types that support versioning in side by side implementations of .NET.

Classes

ComponentGuaranteesAttribute	Defines the compatibility guarantee of a component, type, or type member that may span multiple versions.
FrameworkName	Represents the name of a version of .NET.
ObsoletedOSPlatformAttribute	Marks APIs that were obsoleted in a given operating system version.
OSPlatformAttribute	Base type for all platform-specific API attributes.
RequiresPreviewFeaturesAttribute	Indicates that an API is in preview. This attribute allows call sites to be flagged with a diagnostic that indicates that a preview feature is used. Authors can use this attribute to ship preview features in their assemblies.
ResourceConsumptionAttribute	Specifies the resource consumed by the member of a class. This class cannot be inherited.
ResourceExposureAttribute	Specifies the resource exposure for a member of a class. This class cannot be inherited.
SupportedOSPlatformAttribute	Indicates that an API is supported for a specified platform or operating system. If a version is specified, the API cannot be called from an earlier version. Multiple attributes can be applied to indicate support on multiple operating systems.
SupportedOSPlatformGuardAttribute	Annotates a custom guard field, property or method with a supported platform name and optional version. Multiple attributes can be applied to indicate guard for multiple supported platforms.
TargetFrameworkAttribute	Identifies the version of .NET that a particular assembly was compiled against.
TargetPlatformAttribute	Specifies the operating system that a project targets, for example, Windows or iOS.
UnsupportedOSPlatformAttribute	Marks APIs that were removed or are unsupported in a given operating system version.
UnsupportedOSPlatformGuardAttribute	Annotates the custom guard field, property or method with an unsupported platform name and optional version. Multiple attributes can be applied to indicate guard for multiple unsupported platforms.
VersioningHelper	Provides methods to aid developers in writing version-safe code. This class cannot be inherited.

Enums

ComponentGuaranteesOptions	Describes the compatibility guarantee of a component, type, or type member that may span multiple versions.
ResourceScope	Identifies the scope of a sharable resource.
